Yes. The amount of air passing the outside of the container/object is far greater than that contained inside. As such the humidity in the contained air will be far less (in quantity than the dripping on the outside. Ethanol fuel will absorb a % of water hold it in suspension without freezing. Where it is used there is no need for "dry Gas" or "Heat". If the container is full, the volume of moisture laden air is smaller. If the container is almost empty, the opposite is true, and the remaining fuel is more contaminated. At some point the moisture will overwhelm the Ethanol and makes a mess. From EPA memo: "As an example, at 60 degrees F, water can be absorbed by a blend of 90% gasoline and 10% ethanol up to a content of 0.5 volume percent before it will phase separate. This means that approximately 3.8 teaspoons of water can be dissolved per gallon of the fuel before the water will begin to phase separate." If it gets to that point, the water will pull ethanol out of the gasoline and make a snotty substance that is way bad. Any temperature change in the location of the container (or transmission case etc.) will breathe. In goes the moisture, out goes the drier air, leaving moisture behind. Over a period of years, gallons of water can accumulate in tractor transmissions from this action, especially if it is a little used tractor and never operates at load for hours. Jim

Today's Featured Article - Timing Your Magneto Ignition Tractor - by Chris Pratt. If you have done major engine work or restored your tractor, chances are you removed the magneto and spark plug wires and eventually reached the point where you had to put it all back together and make it run. On our first cosmetic restoration, not having a manual, we carefully marked the wires, taped the magneto in the position it came off, and were careful not to turn the engine over while we had these components off. We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
